Hi Isaiah,
You are talking about the pause in between each session where you see a white screen with the message "Press mouse button or spacebar to proceed to the next lesson," right?
If this is what you meant by "stopping," I'd like to clarify that this is not an error. Little Math does pause in between each session (or "part") of a lesson, and to continue the lesson you just need to do as instructed in the screen (i.e, press mouse button or your spacebar).
In case you'd like to know which keys you can use during playback, you may refer to your Little Math manual by opening Little Math and going to the HELP screen, or you can go here:
